Which title denotes one who is a senior church leader and often holds influence over multiple congregations?

The title that denotes a senior church leader with influence over multiple congregations is a bishop. Bishops typically are responsible for overseeing a diocese, which comprises several local churches, and they play a crucial role in church governance, spiritual leadership, and religious rites. They ensure that the teachings and practices within their jurisdiction align with the doctrine of their denomination and hold authority to ordain clergy within their diocese.

In contrast, while cardinals are also senior church leaders, their primary role is often within the Roman Catholic Church's hierarchy, specifically, they serve as advisors to the pope and are usually not assigned to multiple congregations in the same way as bishops. Ministers and pastors generally serve individual congregations, focusing on local church leadership and congregational needs rather than having authority over multiple church communities. This distinction clearly positions bishops as the leaders who have broader responsibilities and influence beyond a single congregation.
